The new skill progression, which is also due to the large amount of things that the two of them have collected about bow and arrow skills, is the role of the territory. Without these, it would not be easy for the two of them to improve their advanced skills.

Calm the mind: improve concentration, improve eyesight, and reduce the influence of foreign objects. It can effectively discover the enemy's rules and greatly improve the probability of discovering the enemy's weaknesses. (Level 31)

Rapid Shot: Increases the rate of fire of the bow and arrows, and has a multi-shot scattering effect, which will reduce the hit rate, reduce the range, and reduce the attack power of the arrows, up to a maximum of five arrows in a volley. (Level 31)

There is no very powerful ability in the introduction of Calm Spirit, but it is the basic ability of the archer, and the overall effect is definitely not as simple as it seems on the surface. And the skill of rapid shooting, in addition to greatly increasing the rate of fire, the remaining multi-shot scattering effect seems to Du You to be a chicken rib.

This salvo of five arrows looks powerful, but it's actually not as effective as using a normal skill to use an area attack.

This aspect of the improvement is a bit of a waste of the improvement effect, but there is no way. Skills are like that, once you have advanced and improved, it is impossible to go back, unless you relearn new skills.

Among the advanced skills of the two people, only one locking skill is still at the full level and has not been improved, and the other skills have been advanced. And his advanced skills, which are not at full level now, can continue to advance.

This kind of improvement in heritage, as a whole, has improved his strength a lot.

Even his basic skills have changed, I don't know when, his basic swordsmanship has been improved by a level again, it has reached level 9, obviously it has not been improved, but with the growth of experience and his own basic attributes, these basic skills will improve themselves, which is not something that Du You can control.

And with the use of the Smolder's Flame Arrow Array, his basic archery skills have finally been upgraded to a level, reaching the height of level 10. It's just that for Du You, this kind of full level is not very helpful to himself.

As for learning advanced archery skills for the sake of a Smolder's Flame Arrow Array, Du You's time was not so sufficient.

"Okay, now that the skills that should be improved have been improved, the next plan is about to begin. But before that, we have to prepare again, after all, that place is still not a small danger. I'm going to move up our ranks to level 36. If it's not enough then, keep improving. ”

The two sisters have no opinion at all, because their skills have almost advanced, and the rest of the skills are advanced to depend on luck, and there is no need to continue to suppress their own level, so everyone has no opinion.

Now it is very safe to increase your level and increase your strength. Moreover, in terms of hunting fourth-order creatures and earning crystal coins, the impact will not be too great, at most a single person can earn a little less, and kill a few more.

It's just that when Du You made a move, his eyes suddenly widened: "What's the matter, why is it so expensive!"

"What's wrong?" Lin Yucha and Lin Yushi asked a little confused.

Du You didn't hide it: "Level 33 to level 34 should have cost 9 times 3, that is, 27 crystal coins, I have already added them to the end, and now one crystal coin is enough, but you look at the prompt, you need 10,000." ”

Du You didn't say his own, but said that the two sisters were at the 9-star level, but the two of them were the same as themselves, and it would cost 10,000 citrine coins to upgrade, which was really unexpected for Du You.

The two of them were also surprised, they never thought that there would be such a change, could it be that the fourth order was different from before.

"We still have a lot of crystal coins, it's better to try it first, anyway, sooner or later we have to upgrade, it's good to learn about it now." "No one told them about this common sense, and they didn't notice it before.

After thinking about it, Du You simply spent 50,000 crystal coins to upgrade, not only his own, but also the two sisters and unicorn bubbles. It's just that after upgrading, Du You found that the upgrade system was restored.

It seems that the 10,000 crystals spent before were just to break this bottleneck. "From the early stage of the fourth order to the middle stage, we need to break a bottleneck, from the middle stage to the late stage, and from the late stage to the consummation. That is, when the two levels of level 36 and level 39 are at their peak, will they also need a crystal coin, in this case, the cost will be large. ”

Next, there was no bottleneck, no high cost, and Du You directly raised the level of the three people to level 36. Sure enough, if you want to continue to level up, the cost will increase again, and it will not be the usual one.

If you want to enter level 37, the cost will become 20,000 citrine coins, otherwise this bottleneck will not be passed.

"I kind of know why many people stay at the fourth order level for a long time and don't improve, it seems that it is not entirely to suppress the level, and the price of this crystal coin is also a very serious problem. ”

After the fourth order, with these bottlenecks, it is too expensive to break through. However, most people are getting higher and higher, but it is becoming more and more difficult to earn crystals, so it is impossible for them to increase their level.

When Du You enhanced his skills, he was completely speechless. "It turns out that the real big head is here, and the cost of skills can never be compared to the upgrade of the class level itself. Du You smiled wryly.

It turns out that there is also a bottleneck in the middle of improving his skills from level 33 to level 34, and it also needs to be spent. However, unlike the level itself, the cost of different skills is also different. His skills are all 10 stars, so there is no one who spends less than 10,000 citrine coins, and the most is his own Flame of Destruction, probably because the skills are too strong, and 30,000 citrine coins are needed to advance.

Du You endured the pain and improved his skills, and then the level increase really returned to normal. However, after these skills reach level 36, they have to continue to advance, and the price is really twice as high as the previous bottleneck.

There is only one level, Du You is different, there are two professions to upgrade, but it is also 20,000 crystal coins. But there are more skills, and the more advanced skills there are, the greater the cost of upgrades, which is simply a bottomless pit.

The overall number of skills is not too much, but I am afraid that I have more advanced and successful skills than most people. This costs exclusive crystals, and the traded citristine coins cannot be used.

Du You now understands that if a professional wants to upgrade, it is really a threshold step by step, and each threshold is very exaggerated. I thought I was already rich, but now it seems that I am far behind.
